Technical field

The present invention relates to metallurgy rolling technical fields, more specifically to a kind of novel rolling mill universal-joint spindle flat head sleeve.

Background technique

Main transmission universal-joint spindle is in metallurgy rolling field using very extensive, and flat head sleeve is as connection roll and universal-joint spindle One of critical component, be mainly used for transmitting the interaction and torque between main transmission universal-joint spindle and roll.It was rolling Cheng Zhong, in order to obtain the rolled form of very accurate size, knurling through rolling after a period of time can all have certain abrasion, Deformation, needs to change roll or knurling meets size requirements.Roll is realized using flat head sleeve with coupling for universal-joint spindle, is rolled The flat head sleeve cooperation of the homalocephalus and universal-joint spindle of roller is very accurate, and for the needs of roll assembly, flat head sleeve inner hole and roll are flat The fit form of head is mostly clearance fit or transition fit on arc-shaped working face and plane.The drive of main transmission universal-joint spindle is rolled When roller carries out rolling operation, what is be prone to wear first is plane working face；Simultaneously as homalocephalus positions in flat head sleeve without axle center The circular arc working face of device, flat head sleeve and homalocephalus cooperation also can gradually generate the opposite sliding along main shaft axial direction；Cause This, gradually forms wearing clearance between 2 working face of homalocephalus and flat head sleeve inner hole serial number.Since abrasion causes real work area to subtract It is small, it is gradually expanded along with the gap between flat head sleeve inner hole plane and homalocephalus working face, the gap punching generated in operation process It hits increasing, thus the amplitude of main transmission torsional oscillation is caused to incrementally increase, to accelerate the abrasion between flat head sleeve and homalocephalus, such as This vicious circle, one of the main reason for becoming roll main transmission part fatigue failure, and the quality of rolled products can be controlled Have an adverse effect.
